Research summary
Transparent conductive graphene films fabricated from exfoliated graphite oxide followed by thermal reduction were demonstrated as electrodes for solid-state dye-sensitized solar cells, showing conductivity of 550 S/cm, >70% transparency over 1000-3000 nm, high chemical/thermal stability, ultrasmooth surface and tunable wettability [1]. A Chemical Reviews article covered graphenes as a potential electronics material [2]. A JACS paper reported prompt electrochemical exfoliation of graphite in aqueous solutions of inorganic salts ((NH4)2SO4, Na2SO4, K2SO4) to produce graphene at >85% yield (<=3 layers) with lateral sizes up to 44 microns, low oxidation (C/O ratio 17.2), hole mobility 310 cm2 V-1 s-1 and 11 ohm/sq films on A4-size paper [7]. A Chemical Society Reviews article reviewed nanographene chemistry, summarizing non-conventional synthetic routes, structures with 7- or 8-membered rings, selective heteroatom doping, and direct edge functionalization [6]. Self-organized discotic liquid crystalline hexabenzocoronene combined with a perylene dye was used to fabricate solution-processed organic photovoltaic films with vertically segregated perylene/hexabenzocoronene phases and large interfacial area, achieving external quantum efficiencies >34% near 490 nm [3]. A Chemical Reviews article reviewed pyrene-based materials for organic electronics [5]. 3D N-doped graphene aerogel-supported Fe3O4 nanoparticles were demonstrated as oxygen-reduction electrocatalysts in alkaline media, with more positive onset potential, higher cathodic current density, lower H2O2 yield and higher electron-transfer number than Fe3O4 on N-doped carbon black or N-doped graphene sheets, highlighting the role of the 3D macroporous carbon support [4].
